This application is a continuation of U.S. application Ser. No. 15/489,890, which was filed on Apr. 18, 2017. The entire disclosures of U.S. application Ser. No. 15/489,890 are incorporated herein by reference.
The present invention generally relates to automobiles and, more specifically, to a cognitive system and method that provides problem resolution by sound analysis and classification for automobiles.
There are many sources of noise in a vehicle. They include the engine, driveline, tire contact patch and road surface, brakes and the wind. Noise from cooling fans, or the heating ventilation and air conditioning (HVAC) system, alternator and other engine accessories is also fairly common. Many problems are generated as either vibration or noise, transmitted via a variety of paths, and then radiated acoustically into the cabin. These are classified as “structure-born” noises. Others are generated acoustically and propagated by airborne paths. Structure-born noises are attenuated by isolation, while airborne noise is reduced by absorption or through the use of barrier materials. Vibrations are sensed at the steering wheel, the seat, armrests or the floor and pedals. Some problems are sensed visually, such as the vibration of the rear-view mirror or header rail on open-topped cars.

Turning now to an overview of technologies specifically relevant to aspects of the invention, noises in a vehicle can be tonal in the case of engine noise or broadband in the case of road noise or wind noise. Some resonant systems respond at characteristic frequencies, but in response to random excitation. Therefore, although they look like tonal problems on any one spectrum, their amplitude varies considerably. Other problems are self-resonant, such as whistles from antennas. Tonal noises are often harmonic. Instruments that can be used to measure noises in a vehicle include microphones, accelerometers and force gauges or load cells. Nevertheless, there remains a need for complex diagnoses of unusual or “out-of-specification” sounds in an automobile that is based on analytics and classification of such sounds in order to yield performance predictions (e.g., of a given repair based on driving habits of the operator).
Turning now to an overview of the aspects of the invention, one or more embodiments of the invention address the above-described shortcomings of the prior art by providing for analysis and classification of sounds for an automobile so that certain problems that could be associated with certain sounds can be addressed and resolved in a timely manner. A cognitive method is defined that provides for problem resolution by sound analysis and classification as well as a machine learning process that arises from continuous updates made to a sound library following real-time sound capture classification as well as additional sound library updates from owner input, social forums and auto manufacturers and mechanics. The cognitive method also yields performance predictions of a given repair based on machine learning of the driving habits of each of the operators.
The above-described aspects of the invention address the shortcomings of the prior art by providing for an automobile that includes an audio input receptive receiver, a processor and a computer-readable medium. The computer-readable medium has a local database and program instructions stored thereon. When executed, the program instructions cause the processor to perform a method. The method includes causing the receiver to receive an audio input, determining whether the audio input is distinct from sounds stored in a library that includes the local database and breaking the audio input up into constituent segments in an event the audio input is distinct from sounds stored in the library. The method further includes determining whether any of the constituent segments are unassociated with known sources and determining whether present conditions, which were in effect during the receiving of the audio input, are similar to prior conditions, which were in effect during a previous audio input reception, in an event constituent segments are unassociated with the known sources. In addition, the method includes matching those constituent segments unassociated with the known sources to remotely stored or recognized sounds in an event the present and prior conditions are similar.
Turning now to a more detailed description of aspects of the present invention, with reference to
With reference to
With reference to
The automobile 10 can further include a communications unit 36. The communications unit 36 is coupled to the processor 31 and the computer readable medium 32 and provides for communications between the processor 31 and memory or storage remote from the automobile 10 (e.g., the cloud). Such memory or storage remote from the automobile 10 and the local database 320 can be provided as components of a library 37 of sounds and other related information.
With reference to
In an event the audio input is determined at block 403 to be indistinct from or matched with sounds stored in the library 37 or the local database 320, information associated with or otherwise related to the stored sounds is queried (see, e.g., the additional information stored with the sounds in the local database 320 of
In accordance with embodiments, the notification and the alarm can both be issued by the output device 35, which, in these cases, acts as a notification and alert output device. In addition, the notification and the alarm can both be configured to include playable recordings of the relevant sounds, descriptions of the relevant sounds, and displayable information which describes the relevant sounds as well as their probable or associated causes. In this way, the sounds can be replayed for an automobile mechanic or service personnel and their recommendations for repairs can either be reliant on the information or cross-checked with the information for verification.
Returning to
In accordance with embodiments, the determining of whether any of the constituent segments are unassociated with known sources of block 410 can be executed in a similar manner as the determinations of block 403. That is, the method can include determining whether any of the constituent segments match sounds stored in the library 37 or the local database 320 and, if so, further determining whether any of the constituent segments matching stored sounds are associated with normal operations or high risk events.
In an event it is determined that the present conditions have not changed from the prior conditions, the method further includes recording the constituent segments which are found to be unassociated with the known sources in block 410 (block 412), matching those constituent segments to remotely stored or recognized sounds (block 413) and storing the constituent segments in the local database 320 along with information relating to the constituent segments (block 414). The matching of the constituent segments with the remotely stored or recognized sounds can be executed, for example, by searching for sounds corresponding to the constituent segments in the cloud or another similar memory or storage unit or by playing the constituent segment for an automobile mechanic or service person that could potentially recognize it.
In accordance with further embodiments and, as shown in
In accordance with further embodiments and, as shown in
In accordance with still further embodiments, the methods described herein with respect to block 418 in particular can be employed to assist an individual with a selection of a best option for a next automobile purchase. Such assistance could be based on the individual's driving habits which are discerned from historical data and from the sounds recorded and analyzed throughout the lifetime of his/her present automobile ownership. For example, if the individual presently owns an automobile with a manual transmission but is not capable of performing well timed or efficient gear shifting to the point that the recorded sounds include high revving sounds and those of a worn out transmission, the method may include recommending an automobile with an automatic transmission as a next purchase.
Another additional feature may include financial optimization-based repair prediction as part of the operations of block 418. Here, driving habits and associated sounds are used as inputs. For example, city driving with be associated with certain recorded sounds such as high frequency stopping and starting whereas highway driving will tend to be associated with more constant sounds. Thus, in the case of brakes becoming worn out, a predominance of recorded sounds which suggest mostly city driving will result in a much earlier recommendation for brake service as compared to a predominance of highway driving (e.g., 500 miles versus 3000 miles).
The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instruction by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
